Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present utility model more clear, the technical solutions in the embodiments of the present utility model will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described above are part of the embodiments of the present invention, but not all of the embodiments. The embodiments in the basic utility model, and all other embodiments obtained by those of ordinary skill in the art without creative work, fall within the protection scope of the present invention.

As shown in Figures 1 and 2, the figure includes a base 13 and a conveyor belt 1 for screw conveying. One side of the end of the conveyor belt 1 is provided with an adsorption device 3, and the other side is provided with a workbench 11. The adsorption device 3 Located below the conveyor belt 1, a screw mounting mechanism 5 is provided above the worktable 11, and the front end of the adsorption device 3 is connected to a nail suction pipe 8. As shown in FIG. 3, the conveyor belt 1 includes a concave center. The V-shaped part and the middle of the V-shaped part are provided with a through slot 2 , the worktable 11 is provided with a placement slot 9 for placing the workpiece, and two sides of the placement slot 9 are provided with clamping cylinders 10 for clamping screws. The screw is transported through the conveyor belt 1 and transported to the baffle plate 4, the screw is sucked out by the adsorption device 3 at the lower end of the conveyor belt 1, and then transferred to the clamping cylinder 10 after being sucked out, and is clamped by the clamping cylinder 10. The device 3 is withdrawn, and the screw is fastened to the workpiece by the screw mounting mechanism 5 .

When the screw mounting mechanism 5 needs to adjust the position, the screw mounting mechanism 5 is fixed on the lateral shift rod 6 for adjustment, and the screw mounting mechanism 5 is adjusted to the top of the nail suction pipe 8, take the screw, and then move to the workpiece mounting hole ,Mounting screws.
